There are a lot of knowledge in terms of the manufacturing process the rubber roller, Here I will introduce some of the key information in this regard. Surface treatment step manufacturing process Cots: remove powder adhering to the surface, thoroughly washed plastic important work is outside the roll surface polishing process. Demanding products but also further for polishing the surface, or surface coating resin paint, latex materials, magnetic, electrostatic powder and the like. It also needed to be plated with a coating, or chemical oxidation treatment, in order to achieve a sense of light, corrosion, magnetic and electrical conductivity and other functions. Cots final steps of manufacturing the surface treatment is the most critical step. Surface grinding conditions directly about the use of performance cot and product quality. Currently grinding many different ways, but mainly mechanical turning and grinding, for grinding method, grinding tools and abrasive used is very important.
